A friend and I were just watching this video about Horizon Worlds.

Does anybody have any insight into why it looks the way it does?

A small game development team could make some dramatic improvements to this.

Do they not have game developers on the team?

Is there no art director?

Why is there no lighting?

Why are the characters wrists all held unnaturally?

Why do the football emotes float up into their heads?

What does a football mean?
